In an ambitiously noble effort to cut down the enveloping surge of drugs-related violence running amok throughout the crime-addled streets of Mexico City, chief of police Joel Ortega has announced that anyone prepared to surrender a high-calibre weapon, such as a machine gun, will receive a free computer in exchange. And, perhaps in the interests of scale and fair play, anyone turning in a smaller calibre handgun will be presented with either cash remuneration or an Xbox videogame console.
